I actually painted this from a photo that I took the day before. Weather was good that day but not good on our usual plein air painting day of Friday. Its along Schoolhouse Road between Analy High School and Occidental Road here in Sebastopol, CA. There is a large dairy farm on the road and lots of fields with cows along the Laguna de Santa Rosa. My palette for this painting is phthalo blue, Cadmium yellow light, Cadmium red light and Titanium white. I use Gamblin oil paint and mix all of my colors with the three colors.
